FIELD OF THE INVENTION

The present invention relates to a silver halide color photosensitivematerial and, more particularly, to a sensitive material which containsa hydrazine compound to reduce color stain and color fog and to excertan improved storage stability.

BACKGROUND OF THE INVENTION

A silver halide color photosensitive material has so far been well-knownto generate undesirable color stain between silver halide emulsionlayers different in color sensitivity. As a means to inhibit the colorstain, there is proposed, e.g., the method of using hydroquinonecompounds in U.S. Pat. No. 4,732,845. Although hydroquinone compoundshave some effect upon inhibition of color stain, they have drawbacks,e.g., of generating colored matter after performing their function ascolor stain inhibitor and causing undesirable changes in photographicproperties during preparation and storage of sensitive materials.

On the other hand, EP-A2-0338785, JP-A-03-164735 (the term "JP-A" asused herein means an "unexamined published Japanese patent application")and JP-A-05-232651 disclose the use of nondiffusible hydrazine compoundsas color fog inhibitors. Although the nondiffusible hydrazine compoundsdisclosed therein include some phosphorylhydrazine compounds, thosephosphorylhydrazine compounds have little effects on the inhibition ofcolor fog. Therefore, introduction of further improvements in them hasbeen requested. Further, JP-A-60-140340, JP-A-63-223744, JP-A-63-286840,JP-A-63-234244, JP-A-63-306438, JP-A-05-165134, JP-A-05-197091,JP-A-05-142688, JP-A-02-1834 and so on use hydrazine compounds asnucleation agent in photographic systems, and some phosphorylhydrazinecompounds are presented therein. However, those compounds react directlywith silver halides to cause alterations in photosensitivity.Accordingly, they cannot answer the purposes of the present invention.As for the use in systems other than the photographic system, U.S. Pat.No. 4,203,932 demonstrates that phosphorylhydrazines are effectiveinsecticides. However, none of the above-cited references have anydescriptions of the compounds having the structure according to thepresent invention, or the structure in which hydrazine moieties areattached directly to a phosphorus atom. Therefore, the compounds of thepresent invention have structural novelty, and it was unexpected thatthese compounds could solve the aforesaid problems in the photographicsystem.

SUMMARY OF THE INVENTION

A first object of the present invention is to provide a photosensitivematerial which is reduced in color stain and color fog and has excellentcolor reproducibility.

A second object of the present invention is to provide a photosensitivematerial which has slight changes in photographic properties duringproduction and storage thereof.

A third object of the present invention is to provide compounds whichenable the realization of the foregoing objects of providingphotosensitive materials having the properties described above.

The above-described objects are attained with a silver halide colorphotosensitive material having on a support at least one photosensitivesilver halide emulsion layer, said material containing at least onenondiffusible compound represented by the following formula (I), (I-1)or (I-2): ##STR4## wherein R¹ represents an aryl group or a heterocyclicgroup, R² represents an alkyl group, a cycloalkyl group, an alkoxy groupor an aryloxy group, R³ represents an alkyl group, a cycloalkyl group,an aryl group or a heterocyclic group and X represents an oxygen atom ora sulfur atom; provided that R³ does not represent a phenyl group whenR² represents a phenoxy group: ##STR5## wherein R¹ represents the samegroup as R¹ in the formula (I); A¹ and A² each represents a hydrogenatom or a hydrolyzable group; X represents the same atom as X in theformula (I); and Y¹ represents atoms completing a phosphorusatom-containing heterocyclic ring: ##STR6## wherein R¹ represents thesame group as R¹ in the formula (I); R"² represents an alkyl group, acycloalkyl group, an aryl group, a heterocyclic group, an alkoxy groupor an aryloxy group; A¹ and A² each represents the same meaning as A¹and A² in the formula (I); G represents a carbon atom or a phosphorusatom; X represents the same atom as X in the formula (I); when Grepresents a carbon atom, m is 2 and n is 0; when G represents aphosphorus atom, m is 2 and n is 1, or m is 3 and n is 0; and when m is2 or more, two or three R¹ N(A¹)N(A²)-groups may be the same ordifferent.

Preferably, it is an alkyl group containing1 to 60 carbon atoms, with specific examples including a methyl group,an ethyl group, a propyl group, an iso-butyl group, a tert-butyl group,a 2-ethylhexyl group, a nonyl group, an undecyl group, a pentadecylgroup, a n-hexadecyl group and a 3-decanoylamidopropyl group. When R"²represents a cycloalkyl group, the cycloalkyl group may be a substitutedone or an unsubstituted one. Preferably, it is a cycloalkyl groupcontaining 3 to 60 carbon atoms, with specific examples including acyclopropyl group, a 1-ethylcyclopropyl group, a cyclopentyl group and acyclohexyl group. When R"² is an aryl group, examples of its aryl moietyinclude the aryl groups instanced in the description of R¹, excluding aphenyl group, and examples of its substituent part include the samegroups as recited in the description of substituent(s) which R¹ canhave. When R"² is a heterocyclic group, examples of its heterocyclicmoiety include the heterocyclic groups instanced in the description ofR¹, and examples of its substituent part include the same groups asrecited in the description of substituent(s) which R¹ can have.

Each of the groups represented by R¹ may have substituent(s), and tosuch substituent(s) can be applied the groups recited above as thesubstituent(s) which R¹ can have. As examples of more preferable groupsas the substituent(s), mention may be made of an alkyl group, an alkoxygroup, an aryloxy group, an acyl group, an alkoxycarbonyl group, anaryloxycarbonyl group, a carbamoyl group, a sulfonyl group, a sulfamoylgroup, a cyano group, a carboxyl group and a hydroxyl group. Of thesegroups, an alkyl group, an alkoxy group and an alkyloxycarbonyl groupare favored in particular.

As for the hydrolyzable groups represented by A¹ and A², a sulfonylgroup, an acyl group and an oxazolyl group are specific examplesthereof. However, hydrogen atoms are preferred as A¹ and A².

It is preferable for at least either R¹ or R"² that a ballast groupcommonly used for nondiffusible photographic additives, such ascouplers, be incorporated therein. Such a ballast group is a groupcontaining at least 8 carbon atoms and has no adverse effect onphotographic properties, and can be chosen from among, e.g., an alkylgroup, an alkoxy group, an aryl group, an aryloxy group, an amido group,an ureido group, a sulfonamido group, an ester group, a sulfonyl group,an acyl group, a hydroxyl group and combinations of two or more thereof.

As for the combination of R¹ and R"², a case in which both are arylgroups is desirable.

Of the compounds represented by formula (I-2), those represented by thefollowing formula (II-2) are preferred over the others: ##STR12##wherein R"² has the same meaning as R"² in formula (I-2); m is 2 or 3; nis 1 when m is 2, and n is 0 when m is 3; r is an integer from 0 to 5;and R"³ represents a substituent, and when r represents 2 or more, aplurality of R"³ groups may be the same or different.

Examples of a substituent preferred as R"³ in formula (II-2) includethose recited as substituent(s) which R¹ in formula (I-2) can have. Morepreferably, R"³ is an acylamino group, a sulfonamido group, an alkoxygroup, an alkyl group or a chlorine atom.

r in formula (II-2) is preferably 1, 2 or 3.

Of the compounds represented by formula (II-2), compounds represented byformula (III-2) are preferred over the others: ##STR13## wherein R"⁴represents an alkyl group or an aryl group, and R"³ and r have the samemeanings as R"³ and r in the formula (II-2) respectively.

The alkyl or aryl group represented by R"⁴ is preferably chosen fromthose cited as examples of an alkyl or aryl group represented by R"² informula (I-2).

As for the alkyl group represented by R"⁴, a secondary alkyl orcycloalkyl group containing 3 to 30 carbon atoms is more preferred.

As for the aryl group represented by R"⁴, a substituted or unsubstitutedphenyl group is more preferred. Examples of group(s) by which the phenylgroup may be substituted include those recited above as substituent(s)which R¹ in formula (I-2) can have. Of those substituent groups, analkyl group (including those containing 1 to 16 carbon atoms, such asmethyl, isopropyl, tert-butyl, 2-ethylhexyl, cyclohexyl, dodecyl, etc.),an alkoxy group (including those containing 1 to 16 carbon atoms, suchas methoxy, isopropoxy, cyclohexyloxy, hexadecyloxy, etc.) and a halogenatom (e.g, chlorine, bromine, fluorine) are preferred over the others.

In formula (III-2), it is preferable for r to be 1.

Sample Nos. 102 to 116 were prepared in the same manner as Sample No.101, except that the color mixing inhibitor Cpd-A used in the eighthlayer and the thirteenth layer of Sample No. 101 was replaced byequimolar amounts of Comparative Compound A, Comparative Compound B andthe present compounds as set forth in Table 4, respectively.

Each of the thus prepared Sample Nos. 101 to 116 was cut into strips.One strip of each sample was subjected to wedge exposure through a redfilter, and examined for minimum density of the cyan color-forminglayer. The extent of color mixing caused in the red-sensitive layer bythe green-sensitive layer was evaluated by the minimum density examined.Another strip of each sample was subjected to wedge exposure through agreen filter, and examined for minimum density of the magentacolor-forming layer, thereby evaluating the extent of color mixingcaused in the green-sensitive layer by the blue-sensitive layer.

Still another strip of each sample was stored for 1 week under thecondition of 45° C.-80% RH, then exposed to white light through a wedge,and compared with that of the other strip of each Sample which wasstored at 25° C., thereby evaluating the keeping quality of each sample.The photographic processing adopted in these examinations is describedbelow. The results obtained are shown in Table 4.

As can be seen from Table 4, Sample Nos. 104 to 116 in which were usedthe color mixing inhibitors of the present invention had excellentability to inhibit the interlayer color mixing, and suffered a smallchange by storage in the developed color density of a magentacolor-forming layer. Therefore, they had a slight change in gradation.Of the samples according to the present invention, Sample Nos. 109 to116 have proved to be more excellent in ability to inhibit the colormixing and in keeping quality.

EXAMPLE 2

Samples A, B and C were prepared in the same manner as Sample No. 101 ofExample 1 in JP-A-06-236014, except that the Compound Cpd-1 in the 6thand 10th layers was replaced by the present compound (1), (8) and (13)respectively. These samples A, B and C were exposed anddevelopment-processed in the same manners as in Example 1 of the patentgazette cited above. Therein, the results similar to in Example 1 of thepresent invention were obtained.

EXAMPLE 3

Preparation of Sample Nos. 104' to 116':

Sample Nos. 104' to 116' were prepared in the same manner as Sample No.101 prepared in Example 1, except that the color mixing inhibitor Cpd-Aused in the eighth layer and the thirteenth layer of Sample No. 101 wasreplaced by equimolar amounts of the present compounds as set forth inTable 5, respectively.

Each of the thus prepared Sample Nos. 104' to 116' as well as 'SampleNos. 101 to 103 prepared in Example 1 was cut into strips. One strip ofeach sample was subjected to wedge exposure through a red filter, andexamined for minimum density of the cyan color-forming layer. The extentof color mixing caused in the red-sensitive layer by the green-sensitivelayer was evaluated by the minimum density examined. Another strip ofeach sample was subjected to wedge exposure through a green filter, andexamined for minimum density of the magenta color-forming layer, therebyevaluating the extent of color mixing caused in the green-sensitivelayer by the blue-sensitive layer.

As can be seen from Table 5, Sample Nos. 104' to 116' in which were usedthe color mixing inhibitors of the present invention had excellentability to inhibit the interlayer color mixing, and suffered a smallchange by storage in the developed color density of a magentacolor-forming layer. Therefore, they had a slight change in gradation.Of the samples according to the present invention, Sample Nos. 109' to116' have proved to be more excellent in ability to inhibit the colormixing and in keeping quality.

EXAMPLE 4

Samples A', B' and C' were prepared in the same manner as Sample No. 101of Example 1 in JP-A-06-236014, except that the Compound Cpd-1 in the6th and 10th layers was replaced by the present compound (1)', (8)' and(13)' respectively. These samples A', B' and C' were exposed anddevelopment-processed in the same manners as in Example 1 of the patentgazette cited above. Therein, the results similar to in Example 3 of thepresent invention were obtained.

EXAMPLE 5

1) Support

The support used in this example was prepared in the following manner:100 Parts by weight of a polyethylene-2,6-naphthalate polymer and 2parts of a ultraviolet absorbent, Tinuvin P.326 (trade name, a productof Ciba-Geigy) were dried, and then fused at 300° C. Thereafter, thefused matter was extruded from a T-die, and elongated by a factor of 3.3in the longitudinal direction at 140° C., followed by elongation by afactor of 3.3 in the horizontal direction at 130° C. Further, the thuselongated film underwent 6-second thermal setting at 250° C. to give aPEN film having a thickness of 90 μm. Additionally, appropriate amountsof blue, magenta and yellow dyes (Dyes I-1, I-4, I-6, I-24, I-27 andII-5 described in Kokai Giho No. 94-6023) were added to the polymer inadvance of the extrusion. Furthermore, the PEN film was wound onto astainless roll having a diameter of 20 cm, and thereon was conferred48-hour heat history at 110° C. to render the film hard to curl.

2) Formation of Subbing Layer

Both surfaces of the support prepared above were subjected to a coronadischarge treatment, a UV discharge treatment, and further a glowdischarge treatment. The thus treated support was coated with a 10 cc/m²of subbing solution wherein were contained 0.1 g/m² of gelatin, 0.01g/m² of sodium α-sulfodi-2-ethylhexylsuccinate, 0.04 g/m² of salicylicacid, 0.2 g/m² of p-chlorophenol, 0.012 g/m² of (CH₂ ═CHSO₂ CH₂ CH₂NHCO)₂ CH₂ and 0.02 g/m² of a polyamideepichlorohydrin polycondensate(by means of a bar coater) on the side which had been the hightemperature side in the aforesaid elongation step. The thus coatedsolution was dried at 115° C. for 6 minutes (the temperature of therollers and conveying apparatus installed in the drying zone was set at115° C.).

3) Formation of Backing Layer

After forming the subbing layer on one side of the support, the otherside of the support was provided with a backing layer constituted ofantistatic, magnetic recording and slipping layers which had thefollowing compositions respectively.

3-1) Formation of Antistatic Layer:

The back surface of the support was coated with 0.2 g/m² of a dispersionof finely divided tin oxide-antimony oxide complex powder having anaverage grain diameter of 0.005 μm and a specific resistance of 5 Ω.cm(secondarily aggregated grain size: about 0.08 μm), 0.05 g/m² ofgelatin, 0.02 g/m² of (CH₂ ═CHSO₂ CH₂ CH₂ NHCO)₂ CH₂, 0.005 g/m² ofpolyoxyethylene(polymerization degree: 10)-p-nonylphenol and resorcinol.

3-2) Formation of Magnetic Recording Layer

0.06 g/m² of cobalt-γ-iron oxide (having the specific surface area of 43m² /g, the major axis of 0 14 μm, the minor axis of 0.03 μm, thesaturation magnetization of 89 emu/g, the Fe⁺² /Fe⁺³ ratio of 6/94 andthe grain surface treated with aluminum oxide and silicon oxide in theamount corresponding to 2 wt. % of the iron oxide) covered with3-poly(polymerization degree: 15)oxyethylenepropyloxytrimethoxysilane(15 wt. %) was coated by means of a bar coater together with 1.2 g/m² ofdiacetyl cellulose (the dispersion of the iron oxide thereinto wascarried out with an open kneader and a sand mill), 0.3 g/m² of C₂ H₅C(CH₂ OCONHC₆ H₃ (CH₃)NCO)₃ as a hardener and a mixture of acetone,methyl ethyl ketone and cyclohexanone as a solvent, thereby forming amagnetic recording layer having a thickness of 1.2 μm. Additionally, 10mg/m² of silica grains (0.3 μm) as a matting agent and 10 mg/m² ofaluminum oxide (0.15 μm) coated with 3-poly(polymerization degree:15)oxyethylenepropyloxytrimethoxysilane (15 wt. %) as an abrasive werealso added thereto. The drying was carried out at 115° C. for 6 minutes(the temperature of the rollers and conveying apparatus installed in thedrying zone was set at 115° C.). The gain in color density D^(B) of thethus formed magnetic recording layer upon exposure to X-light (bluefilter) was about 0.1. Further, the saturation magnetization of themagnetic recording layer was 4.2 emu/g, the coercive force thereof was7.3×10⁴ A/m, and the rectangular ratio was 65%.

3-3) Formation of Slipping Layer

Diacetyl cellulose (25 mg/m²) and a mixture of C₆ H₃ CH(OH)C₁₀ H₂₀COOC₄₀ H₈₁ (Compound a, 6 mg/m²) with C₅₀ H₁₀₁ O(CH₂ CH₂ O)₁₆ H(Compound b, 9 mg/m²) were coated. Additionally, the mixture wasprepared as follows: Compounds a and b are fused at 105° C. in axylene/propylene monomethyl ether (1/1) mixture, poured and dispersedinto propylene monomethyl ether (10 times the amount of the pouredmatter) having ordinary temperature, and further made into a dispersion(average particle size: 0.01 μm) in acetone. Further, silica grains (0.3μm) as a matting agent and aluminum oxide (0.15 μm) coated with3-poly(polymerization degree: 15)oxyethylene-propyloxytrimethoxysilane(15 wt. %) as an abrasive were added to the dispersion so that each ofthem might have a coverage rate of 15 mg/m². The coating was dried at115° C. for 6 minutes (the temperature of the rollers and conveyingapparatus installed in the drying zone was set at 115° C.). The thusformed slipping layer had a kinematic friction coefficient of 0.06 (5 mmφ stainless ball, 100 g of load, 6 cm/min. of speed) and a staticfriction coefficient of 0.07 (Clip method). With respect to the frictionbetween the slipping layer and an emulsion layer described below, thekinematic friction coefficient was 0.12. That is, the slipping layerformed had excellent characteristics.

4) Formation of Photosensitive Layer

On the side opposed to the backing layer formed in the above-describedmanner, the same emulsions as used for preparing Sample No. 101 inExample 1 were coated over the support in the multilayer form to prepareSample No. 201'. Similarly thereto, Sample No. 216' was prepared usingthe same emulsions as used for preparing Sample No. 116' in Example 3.

5) Evaluation

These samples were evaluated by the same methods as adopted in Example3. Thus, it has been found that Sample No. 216' had distinctimprovements in color turbidity, photodiscoloration and keeping quality,compared with Sample No. 201'.

EXAMPLE 6

Preparation of Sample Nos. 104" to 116":

Sample Nos. 104" to 116" were prepared in the same manner as Sample No.101 in Example 1, except that the color mixing inhibitor Cpd-A used inthe eighth layer and the thirteenth layer of Sample No. 101 was replacedby equimolar amounts of the present compounds as set forth in Table 6,respectively.

Each of the thus prepared Sample Nos.104" to 116" as well as Sample Nos.101 to 103 obtained in Example 1 was cut into strips. One strip of eachsample was subjected to wedge exposure through a red filter, andexamined for minimum density of the cyan color-forming layer. The extentof color mixing caused in the red-sensitive layer by the green-sensitivelayer was evaluated by the minimum density examined. Another strip ofeach sample was subjected to wedge exposure through a green filter, andexamined for minimum density of the magenta color-forming layer, therebyevaluating the extent of color mixing caused in the green-sensitivelayer by the blue-sensitive layer.

As can be seen from Table 6, Sample Nos. 104" to 116" in which were usedthe color mixing inhibitors of the present invention had excellentability to inhibit the interlayer color mixing, and suffered a smallchange by storage in the developed color density of a magentacolor-forming layer. Therefore, they had a slight change in gradation.Of the samples according to the present invention, Sample Nos. 109" to116" using the present compounds in which both R"¹ and R"² were arylgroups have proved to be more excellent in ability to inhibit the colormixing and in keeping quality.

EXAMPLE 7

Samples A", B" and C" were prepared in the same manner as Sample No. 101of Example 1 in JP-A-06-236014, except that the Compound Cpd-1 in the6th and 10th layers was replaced by the present compound (1)", (8)" and(13)" respectively. These samples A", B" and C" were exposed anddevelopment-processed in the same manners as n Example 1 of the patentgazette cited above. Therein, the results similar to in Example 6 of thepresent invention were obtained.

EXAMPLE 8

Preparation of 1) a support, and formation of 2) a subbing layer and 3)a backing layer [constituted of 3-1) an antistatic layer, 3-2) amagnetic recording layer and 3-3) a slipping layer] were carried out inthe same manners as in Example 5, respectively.

Further, 4) a photosensitive layer was formed on the subbing layer (oron the side opposed to the backing layer). In forming the photosensitivelayer, the same emulsions as used for preparing Sample No. 101 inExample 1 were coated over the support in the multilayer form to prepareSample No. 201". Similarly thereto, Sample No. 220" was prepared usingthe same emulsions as used for preparing Sample No. 116" in Example 6.

These samples were evaluated by the same methods as adopted in Example6. Thus, it has been found that Sample No. 220" had distinctimprovements in color turbidity, photodiscoloration and keeping quality,compared with Sample No. 201".

While the invention has been described in detail and with reference tospecific embodiments thereof, it will be apparent to one skilled in theart that various changes and modifications can be made therein withoutdeparting from the spirit and scope thereof.
